In order to investigate the cooling and heating characteristics of a variable-capacity system A/C using<br/> a digital scroll compressor, the cooling and heating capacities and EER are measured by the<br/> psychrometric calorimeter. The capacity of the system is controlled by the digital scroll compressor,<br/> which is operated by controling PWM valve and the loading vs. unloading time. When the system A/C<br/> is operated under the cooling and heating standard conditions, EER is nearly uniform but cooling<br/> capacity and heating capacity increase at minimum, rated and maximum modes. When the auxiliary<br/> heater is on, at the cold region, the system A/C produces the excellent heating capacity.

In order to investigate the cooling and heating characteristics of a variable-capacity system A/C applying a digital scroll compressor, the cooling and heating capacities and COP are measured by the psychrometric calorimeter. The capacity of the system is controlled by the digital scroll compressor, which is operated by controling PWM valve and the loading vs. unloading time. In the case of unloading compared that of loading, the consumption power of the compressor is about 11% and the capacity variation of the system A/C is within about 1%. When the system A/C is operated under the cooling and heating standard conditions, COP is nearly uniform but cooling capacity and heating capacity increase at minimum, rated and maximum modes. The system A/C applying the digital scroll compressor is effective for the range with high load or the width of large load variation. When the auxiliary heater is on, at the cold region, the system A/C produces the excellent heating capacity.
